Appeal No. 1996-2961
Application No. 08/342,827
said first system yarns being hollow, synthetic
monofilament yarns having an O-shaped cross-section and an
internal core void of at least 16%, being compressible from a
substantially round cross-section to a fully flattened cross-
section when subjected to nip pressures of at least 200 psi,
and being sufficiently resilient to rebound to an uncompressed
state after passing through a press nip; and
said base fabric being woven and finished such that
in said finished base fabric:
portions of said first system yarns which
contact said second system yarns have at least a
partially flattened cross-section, and
said first system yarns remain substantially
unflattened in cross-section thereby defining
resiliently compressible cushioning for enhancing
wet press felt performance in dewatering an aqueous
paper web through a press nip.
The examiner has not applied prior art in the rejection
of the appealed claims.
Appealed claims 15, 16, 23 and 25 stand rejected under
35 U.S.C. § 112, first paragraph. Claims 15-19, 21-23 and 25
stand rejected under the judicially created doctrine of
obviousness-type double patenting as being unpatentable over
claims 1-14 of U.S. Patent No. 5,368,696.
The present application is a continuation of U.S.
Application No. 07/955,513, filed October 2, 1992. The parent
application issued as Patent No. 5,368,696. This patent is
the basis for the examiner's double patenting rejection.
